[Toybox] New tests for dirname and wc

[Felix Janda]

Hello,

attached are some simple tests for dirname and wc and
a fix for a small typo in another test script.

Posix specifies an -m option for wc, which toybox does
not implement. Should there be a test for this, too?

Why do the scripts actually use bash?

Regards,
Felix
